Improving the efficiency of meadow clover production in the conditions of the Sumarokovsky collective farm in the Susaninsky district of the Kostroma region

The article presents the results of research on the influence of various methods of pre-sowing treatment and plant nutrition on increasing seed productivity and yield of green mass of meadow clover of the Soligalichsky local variety. The research was conducted in 2023 in the conditions of the Sumarokovsky collective farm in the Susaninsky district of the Kostroma region. In the conditions of the farm, field experience was laid with the treatment of seeds with a complex of trace elements and ozone by air flow, followed by the introduction of mineral and micronutrients during vegetation. The research results showed a positive effect of the complex of trace elements on the seed productivity of meadow clover, as well as an increase in the yield of green mass through the use of such techniques as seed ozonation and mineral fertilizers.
